OBJECTIVES: The objective of this study is to describe complications associated with the use of two types of silicone oil (SO) (1000 centistokes [cs] and 5000 cs) in vitreoretinal surgery in Oman. MATERIALS AND METHODS: This is a retrospective descriptive study on all patients who underwent vitreoretinal surgeries in which SO injection or removal was done. The study was conducted at Sultan Qaboos University Hospital between January 1, 2010, and December 31, 2017. Demographic data, lens status of the eye at the time of SO injection, type of SO used (1000 cs or 5000 cs), and complications associated with SO were collected. RESULTS: A total of 107 eyes of 103 patients were included in the study. SO 1000 cs was used in 66 eyes and SO 5000 cs was used in 41 eyes. A total of 29 eyes (27%) developed SO-related complications, which included SO emulsification in 14 eyes (13.1%), raised intraocular pressure (IOP) >21 mmHg in 19 eyes (17.8%), and band keratopathy in 4 eyes (3.7%). SO emulsification was seen in eight eyes (12.1%) in whom SO 1000 cs was used and in five eyes (12.2%) in whom SO 5000 cs (P = 1.000). CONCLUSION: SO was found to be a relatively safe adjunct in vitreoretinal surgery. SO-related complications such as SO emulsification, raised IOP, and band keratopathy were observed in less than one-third of study eyes. No difference was noted in emulsification rate between SO 1000 cs and SO 5000 cs. Further studies with larger sample size and longer follow-up period are warranted.
